v SHOE PRESS Ernest bunforcL St. Louis, Mo., assignor to Landis I,Machine Company, St. Louls, Mo. q Application November 12, 1947, SerialN0.'785,209

The invention relatesto shoe presses, such as are commonlyused incementing a shoe sole or half sole to the shoe upper and forotheroperations and of the kind generally described in Patent No.2,268,874, issued January 6, 1942, to C. L. Huntoon, and in. acopending'application Serial No.. 717,946, filed December 23,1946, bythe present inventor -now Patent No. 2,437,942, issuedMarch 16,1948- Themain object of the invention is to equalize the pressure throughoutrthearea 'of. the shoe parts to be cemented together.

In each of the devices described in the above patent and copendingapplication, the last supporting yoke is free to' pivotrelative to theactuating rods and to the deformable cushion. When movement of the lastis opposed by the cushion,

the legs of the yoke connectedto the rods tend to align with the rodsand the toe of the last presses the shoe sole toe portion into thecushion without exerting adequate pressure on the shoe sole rearportion. In attempting to secure adequate pressure on the shoe sole rearportion, the operator may strip the teeth from the gears of theoperating mechanism.

Another object is to overcome these difficulties by providing a lockingadjustment for the yoke to the rods so the last may be fixed at anydesired angle to the cushion.

The above and other detail objects are attained by the structureillustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a shoe press constructed according tothe invention and provided with a last supporting yoke adjustably lockedto the actuating rods.

Figure 2 is a top view of the yoke and associated rods, and

Figure 3 is a transverse section taken approximately on the line 3'3 ofFigure 1.

The shoe press comprises a frame I mounting a support 2 having a rigidtray-like main member 3 and a vertically adjustable segment 4. Thesupport mounts a deformable cushion 8 upon which the bottom of the shoeS may rest. Vertical adjustment of segment 4 distorts cushion 8 andadapts the support for shoes having shanks at diiferent angles to thesoles, that is, for shoes Segment 4 has a depending pin 9 at each of itsends slidably received in bearings III in the rearwardly extending lugsII on member 3. Brackets l2 depend from the underside of member 3 androtatably support a shaft l3 mounting a pair of cams I 4 engaging pins9. Segment 4 is raised and low 9 Claims. (o1. 12-33) ered relative tomain member 3 by rotating shaft l3 and cams by a handle l5. Each cam l4has a series of indentations I6 in its periphery to receive. the endofthe corresponding pin 9 to hold segment 4 in adjusted position. 7

A shaft l1 operated by a handle it is journalled in frame -'I and has aworm l9 inmesh with the teeth of a crank wheel 20-journal1ed in theframe. Rods-2| and 21a at'the sides of the frame are pivotedat one endto wheel crank pin 22 and at the other end to a yoke 23 which may berotated about its longitudinal axis to different positions, as indicatedin dot-dash lines in Figure l, on pins 26 journalled in the rods andheld against lengthwise movement by locking screws 21 in the yoke. Yoke23 has a bayonet joint engagement with the end of an arm 24 on a last 25which may be inserted within the shoe S. A locking bolt 28 through rod2| and through a slotted lug 28 on yoke 23 secures the yoke againstmovement relative to the rods and pro-- vides for adjustment the last atany desired angle to cushion 8.

Rotation of handle l8 causes crank pin 22 to draw rods 2| and Ziadownwardly, thereby applying pressure through last 25 to the interior ofthe bottom of shoe S and thrusts the shoe sole against cushion 8. Yoke23 and last 25 preferably are positioned on rods 2|, 2| a so thatsubstantially uniform pressure is exerted on all parts of the shoe sole.Rods 2|, Zia may be pivoted about crank pin 22 to position last 25forwardly or rearwardly on cushion 8 and to change the direction ofthrust on the last as described in the above patent.

The details of construction may be varied without departing from thespirit of the invention, and the exclusive use of those modificationscoming within the scope of the claims is contemplated.

What is claimed is:

1. In a shoe press, cooperable pressure members, and means for movingone of said members with respect to the other member and comprisingdriving mechanism and an element pivoted to said mechanism and to saidmovable member, there being means to adjustably lock said movable memberto said element at desired angles to said other member.

2. In a shoe press, a last-like pressure member including a yoke andarranged to oppose the inner part of a shoe, a cooperating pressuremember arranged to oppose a corresponding outer part of the shoe,driving mechanism, an elongated element connected at its ends to saiddriving mechanism and to said yoke, said last-like member beingpivotally mounted on said element, and means for locking said last-likemember against pivotal movement on said element.

3. In a shoe press, a stationary pressure member, a movable pressuremember opposing said stationary member, and means for moving saidmovable member relative to said stationary member and comprising adriving mechanism and an elongated element pivoted atone end to saidmechanism and at its other end to said movable member, there being meansto adjustably lock said movable member to said element at desired anglesto said stationary member.

4. In a shoe press, cooperable pressure members, and means for movingone of said members with respect to the other member and comprising 7driving mechanism and an element pivoted to said mechanism and to saidmovable member and arranged to apply pressure through the latter fromdifferent directions when said element is pivoted to difierentpositionson said mechanism, there being means tolock said movable member in aselected angular position relative to said element.

5. In a shoe press, a last-like pressure member including a yoke andarranged to oppose an inner part of a shoe, a cooperating pressuremember arranged to oppose the corresponding outer part of the shoe, adriving mechanism, and linkage connecting saiddriving mechanism and saidyoke, said yoke being mounted adjustably on said linkage, and means forfixing'said yoke to said linkage with said last-like member at desiredangles to said cooperating member.

6. Structure as described in claim 5 in which the yoke is pivoted on thelinkage and the fixing means comprises a manually rotatable frictionclamp spaced from the yoke and linkage pivot.

7. In a shoe press, a last-like pressure member including a yoke andarranged to oppose an inner part of a shoe, a cooperating pressuremember ar- Number ranged to oppose a corresponding outer part of theshoe, a driving mechanism, and linkage connecting said driving mechanismto the ends of said yoke, said yoke being mounted on said linkage forrotation about its axis tending longitudinally of the yoke, and meansfixing the yoke to the linkage with said last-like member at a selectedangle to said cooperating member.

8. In a shoe press, a last-like pressure member including a yoke elementand arranged to oppose an inner part of a shoe, a cooperating pressuremember arranged to oppose a corresponding outer part of the shoe, adriving mechanism, and a rod element connecting said driving mechanismand said yoke element, said yoke element being mounted for pivotalmovement on said rod element and having a' flange extending along saidrod element, one of said elements having an aren ate slot about thepivotal connection between said elements, and means extending throughsaid slot and engaging the other element for locking said elementstogether at desired angles.

9. In a shoe press, aframe forming a support for a shoe, a shaftextending through said frame beneath said support, means for rotatingsaid shaft, cranks on the opposite ends of said shaft, links secured tosaid cranks and extending upwardly therefromat. the .sides of saidsupport, a yoke pivotally connected to the upright ends of said linksand adaptedto mount a last in opposed relation to said support, andmeans for securing said yoke in selected pivotal position on said links.
